I was recently trying to get the Unreal Engine to install but couldn’t even open the launcher. I have now determined what the cause of the problem is. I have a DisplayLink USB monitor, and the drivers for this monitor cause issues with UE4.
I am unsure as to what the issues are, but I am following a thread on the DisplayLink forums: Latest DisplayLink drivers and DirectX fullscreen errors - Page 6 - DisplayLink Forum
If anybody has any advice as to how to make UE4 work with my DisplayLink monitor’s drivers still installed, please let me know. I understand this is mainly DisplayLink’s fault, however I decided to post this here incase anybody else is having similar issues.
I would attach my UE4 log file but it is completely useless (it literally freezes the log file halfway through a line of output thats complaining about a missing file, that clearly hasn’t downloaded yet because the launcher hasn’t run for the first time)
